Use bank data from the chat.
bankbridge command is that command.Read-only. Your agent can see balances and transactions, and nothing can move money, pay a bill, or place a trade. BankBridge doesn’t store your transactions. How it’s secured · Try it with sample data first
Install the command.
curl -fsSL https://bankbridge.money/install.sh | sh
It adds one binary to ~/.local/bin and changes nothing in Aider. Check it with fictional data, no account needed:
bankbridge accounts --demo
Sign in.
Copy an API key from your dashboard, then:
bankbridge login
Or set BANKBRIDGE_API_KEY in your environment.
Run it from Aider.
/run (or !) runs the command and asks whether to add the output to the chat. Say yes, then ask your question.
> /run bankbridge recurring --json Add 1.6k tokens of command output to the chat? (Y)es/(N)o [Yes]: y > Which of these should I cancel to save $100 a month?
Hand it a file for bigger questions.
Export first, then open Aider with the file read-only. /read-only does the same mid-chat.
bankbridge transactions --month 2026-10 -o october.csv aider --read october.csv
The file stays on your disk. We keep no copy.
Let the model suggest commands (optional).
Aider’s model can suggest shell commands, and Aider asks before running each one. To tell it about BankBridge, keep a short conventions file and load it with aider --read CONVENTIONS.md:
Bank data: suggest bankbridge commands. Run `bankbridge --help` to see them. Use --json. Read-only. Positive amounts are money out. If a command prints a warning, a bank may be missing from the result, so say so.
Anything you add to the chat goes to the model provider you configured in Aider, like any other command output.
